DETAILED DESCRIPTION
[0014] In the following detailed description, for purposes of
explanation, numerous specific details are set forth in order to
provide a thorough understanding of the disclosed embodiments. It
will be apparent, however, that one or more embodiments may be
practiced without these specific details. In other instances,
well-known structures and devices are schematically shown in order
to simplify the drawing.
[0015] Please refer to FIG. 1 to FIG. 4. FIG. 1 is a perspective
view of an optical transceiver in accordance with one embodiment of
the disclosure. FIG. 2 is an exploded view of the optical
transceiver in FIG. 1. FIG. 3 is a partial enlarged view of a
casing of the optical transceiver in FIG. 2. FIG. 4 is a partial
enlarged cross-sectional view of the optical transceiver in FIG. 1.
In this embodiment, an optical transceiver 1 is provided. The
optical transceiver 1 includes a casing 10, two fastening members
20, a driving member 30, a restoring member 40 and two elastic
members 50. The optical transceiver 1 is pluggable into a
receptacle (e.g., a receptacle 2 as shown in FIG. 5A). The
receptacle 2 has a fastening portion 21, and the fastening portion
21 has two fastening holes 22. It is worth noting that the numbers
of the fastening members 20 and the fastening holes 22 are not
limited as the result. In other embodiments, the optical
transceiver may have only one fastening member, and the receptacle
may have only one fastening hole.
[0016] The casing 10 has a supporting surface 110, two side
surfaces 120 and a top surface 130. The two side surfaces 120 are
respectively connected to two opposite sides of the supporting
surface 110, and the two side surfaces 120 are located between the
supporting surface 110 and the top surface 130. There is an
accommodating space 140, which is defined between the supporting
surface 110, the side surfaces 120 and the top surface 130. The
casing 10 has two through holes 150 on the supporting surface 110,
and the casing 10 further has two guiding slots 160 respectively
located on the two side surfaces 120. The two guiding slots 160
respectively correspond to the through holes 150. In this
embodiment, an end of the guiding slot 160 is connected to the
through hole 150. The two through holes 150 respectively correspond
to the two fastening holes 22 of the fastening portion 21 when the
optical transceiver 1 is plugged into the receptacle 2 (as shown in
FIG. 5C). In this embodiment, the casing 10 includes a top casing
(not labeled) and a bottom casing (not labeled), and the bottom
casing has the supporting surface 110 and the side surfaces 120.
However, the protective scope of the present disclosure is not
limited to the configuration of the casing 10. In other
embodiments, for example the top casing and the bottom casing could
be integrated into a single unit.
[0017] The two fastening members 20 are movably disposed in the
accommodating space 140 of the casing 10. In detail, the two
fastening members 20 are respectively located in the two guiding
slots 160 on the side surfaces 120. The two fastening members 20
respectively correspond to the two through holes 150. Each of the
fastening members 20 has an assembling hole 210 and a first
inclined surface 220 on an interior surface of the assembling hole
210. The first inclined surface 220 is a part of the interior
surface of the assembling hole 210. The first inclined surface 220
has a start end 221 and a stop end 222 opposite to each other, and
a distance D1 between the start end 221 and the supporting surface
110 is larger than a distance D2 between the stop end 222 and the
supporting surface 110. In other words, an extension direction A of
the first inclined surface 220 and the supporting surface 110 form
an acute angle. However, the assembling hole is optional. In other
embodiments, the fastening member may have no assembling hole, and
the first inclined surface may be located on a corner of the
fastening member.
[0018] In addition, each of the fastening members 20 further has a
guiding inclined surface 230. The driving member 30 includes two
driving assemblies, and each of the driving assemblies includes an
extending arm 310 and a connecting member 320. The extending arm
310 is movably disposed in the accommodating space 140 of the
casing 10. The connecting member 320 is disposed on an end of the
extending arm 310 and extends toward the side surface 120 of the
casing 10. The connecting member 320 is disposed in the assembling
hole 210 of the fastening member 20. In this embodiment, the
connecting member 320 has an enlarged portion 321 on an end away
from the extending arm 310. The fastening member 20 is located
between the enlarged portion 321 and the extending arm 310, and the
enlarged portion 321 is larger than the assembling hole 210, such
that the fastening member 20 is prevented from being separated from
the connecting member 320. The driving member 30 is movable with
respect to the casing 10 along a press direction P to enable the
connecting member 320 to press the first inclined surface 220 of
the fastening member 20, and the press direction P is substantially
orthogonal to a normal direction N of the supporting surface 110 of
the casing 10. While the connecting member 320 presses against the
first inclined surface 220, the connecting member 320 causes the
fastening member 20 to move from a fastened position (as shown in
FIG. 4) to a released position (shown in FIG. 5B) along the guiding
slot 160.
[0019] The restoring member 40 is, for example, an elastic piece.
The restoring member 40 is located in the accommodating space 140
of the casing 10 and disposed on a top surface 130 of the casing
10. When the fastening members 20 are moved toward the top surface
130 of the casing 10, the restoring member 40 is pressed by the
fastening members 20 to store the elastic energy. The restoring
member 40 could help facilitate the movement of the fastening
members 20 away from the top surface 130 while releasing its
elastic energy.
[0020] The two elastic members 50 are, for example, two compression
springs. The elastic members are disposed in the accommodating
space 140 of the casing 10. In detail, the casing 10 further has
two first restricting surfaces 170, and each of the extending arms
310 of the driving member 30 has a second restricting surface 311.
The second restricting surfaces 311 of the two extending arms 310
are respectively face the two first restricting surfaces 170. The
two elastic members 50 are respectively disposed in space between
the first restricting surfaces 170 and the second restricting
surfaces 311.
[0021] Please refer to FIG. 4 and further refer to FIGS. 5A-5C.
FIG. 5A to FIG. 5C are partial enlarged cross-sectional views of
the optical transceiver in FIG. 4 plugged into a receptacle. As
shown in FIG. 4, the fastening member 20 is in the fastened
position. At this moment, the fastening member 20 protrudes through
the through hole 150 of the casing 10, and the connecting member
320 of the driving member 30 is located at the start end 221 of the
first inclined surface 220. The connecting member 320 could be
spaced apart from or in slight contact with the first inclined
surface 220, which could result in no pressure on the first
inclined surface 220.
[0022] Then, as shown in FIG. 5A, the optical transceiver 1 is
plugged into the receptacle 2, and the guiding inclined surface 230
of the fastening member 20 is pressed by an edge of the receptacle
2. Due to the guiding inclined surface 230, the fastening members
20 are able to be moved from the fastened position to the released
position because of the casing 10. While the fastening members 20
are moved from the fastened position to the released position, the
restoring members 40 are pressed by the fastening members 20 to
store the elastic energy. When the fastening members 20 are in the
released position, the fastening members 20 do not block the
receptacle 2, allowing for the casing 10 to be plugged into the
receptacle 2 smoothly.
[0023] Then, as shown in FIG. 5B and FIG. 5C, the casing 10 moves
until the fastening hole 22 of the fastening portion 21 is aligned
with the fastening member 20. As this moment, the restoring member
40 releases its elastic energy to move the fastening member 20 to
penetrate through the through hole 150 and the fastening hole 22.
As a result, the fastening member 20 is moved back to the fastened
position to be fastened with the fastening portion 21 of the
receptacle 2, completing the insertion of the optical transceiver
1.
[0024] It is worth to mention that the guiding slots 160 are
beneficial to guide and position the fastening members 20.
[0025] In addition, the optical transceiver 1 could be pulled out
from the receptacle 2 with the pull of the handle 60. Please refer
to FIG. 6A and FIG. 6B, which are partial enlarged cross-sectional
views of the optical transceiver in FIG. 5C pulled out from the
receptacle. As shown in FIG. 6A, while the extending arm 310 is
moved along the press direction P by the pull of the handle 60, the
connecting member 320 continuously presses the first inclined
surface 220 of the fastening member 20 from the start end 221 to
the stop end 222 so as to move the fastening member 20 from the
fastened position to the released position. When the fastening
member 20 is in the released position, the fastening member 20 is
removed from the fastening hole 22 of the fastening portion 21. As
this moment, the casing 10 is allowed to be pulled out from the
receptacle 2 along the press direction P. In addition, while the
fastening member 20 is moved to the released position, the
restoring member 40 stores the elastic energy when being pressed by
the fastening member 20. When the extending arm 310 is moved along
the press direction P, the second restricting surface 311 of the
extending arm 310 is moved closer to the first restricting surface
170 of the casing 10 to compress the elastic member 50. The elastic
member 50 stores the elastic energy when being compressed.
[0026] Then, as shown in FIG. 6B, the handle 60 is released, such
that the elastic member 50 can release its elastic energy to move
the connecting member 320 in a direction opposite to the press
direction P. In such a case, the connecting member 320 stops
restricting the fastening member 20 so that the fastening member 20
is moved back to the fastened position to penetrate through the
through hole 150 by the elastic energy in connection with the
restoring member 40.
[0027] Further, each guiding slot 160 has two second inclined
surfaces 161, and each of the fastening members 20 further has two
third inclined surfaces 240. As shown in FIG. 6A, the second
inclined surface 161 and the third inclined surface 240 on the
right side of the fastening member 20 are parallel to each other,
and the second inclined surface 161 and the third inclined surface
240 on the left side of the fastening member 20 are parallel to
each other. In other words, these inclined surfaces could render
compatible the guiding slot 160 and the fastening member 20.
Therefore, when the fastening member 20 is in the fastened
position, the two third inclined surfaces 240 of the fastening
member 20 are respectively in tight contact with the second
inclined surfaces 161, which is beneficial to prevent the
electromagnetic interference (EMI). In other embodiments, each of
the guiding slots may have only one second inclined surface, and
each of the fastening members may have only one third inclined
surface.
[0028] Moreover, the casing 10 further has two stopping surfaces
180. When the fastening members 20 are in the released position,
the stopping surfaces 180 are able to stop the movement of the
driving member 30 along the press direction P as the extending arms
310 press against the stopping surfaces 180. Thus, the driving
member 30 is prevented from being damaged when being pulled too
hard.
[0029] According to the optical transceiver as discussed above,
because the distance between the start end and the supporting
surface is larger than the distance between the stop end and the
supporting surface, the driving member is able to move the
fastening member from the fastened position to the released
position by pressing the first inclined surface of the fastening
member. Thus, the fastening member can be engaged with or
disengaged from the fastening portion in a fast and efficient
manner, rendering more convenient the use of the optical
transceiver.
[0030] The embodiments were chosen and described in order to best
explain the principles of the disclosure and its practical
applications, to thereby enable others skilled in the art to best
utilize the disclosure and various embodiments with various
modifications as are suited to the particular use contemplated. It
is intended that the scope of the disclosure be defined by the
following claims and their equivalents.
